FWIW, I have a new Wheezy (3.4.9-rtai-686-pae #1 SMP PREEMPT Debian 3.4.55-4linuxcnc i686 GNU/Linux) install running, now for 2 days 40 min, and it is using no swap. Up until a few minutes ago it was running a web browser, 1 terminal (with top), and 2 instances of glxgears. For the last several minutes I have been doing general browsing and poking around using half a dozen terminal instances and a few file system manger windows. In all that time, it claims to have used no swap at all and 638068 MB ram. This is the ATOM based system I posted about a couple days ago, and has only 2GB of ram. -Tom
